REFLECTOR CONNECTION.

Application filed August 25, 1915.

To all whom it may concern:

Be it known that I, LAURITZ N. ANDER- sen, a citizen of the UnitedStates, residing at lVaterbury, in the county of New Haven and State ofConnecticut, have invented a certain new and useful Improvement inReflector Connections, of which the following is a full, clear, andexact description, reference being had to the accompanying draw ings.

This invention relates generally to port able electric fixtures and moreparticularly to devices employing reflectors or shades; and the objectof the invention is to provide a novel connection between the socket andreflector whereby certain advantageous results are obtained.

One much desired result obtained, is the centering of the incandescentlamp within the reflector.

Another very advantageous result obtained, is the ability to turn thereflector freely upon the lamp and socket so the light can be thrown inany direction, and another result obtained is the provision of a supportfor the lamp socket itself and at the same time provide a furtherconnection for the reflector.

\Vith these objects and results in view my invention consists in thenovel features of construction and arrangement, all of which will befully described hereinafter and pointed outin the appended claims.

In the drawings forming a part of this specification Figure 1 is aperspective view showing the practical application of my i11- vention.Fig. 2 is a sectional view of the reflector and socket holdingconnection, and Fig. 3 is a detail perspective view partly in sectionshowing the parts detached.

It will be understood that this invention is capable of use inconnection with any and all sorts of shades or reflectors to which asleeve or neck can be attached, and in the drawing I have shown oneembodiment of my invention, and in which is illustrated a parabolareflector 10, having an opening 11 produced near one edge thereof toreceive the incandescent lamp socket 12. A short sleeve or neck 13, isfixed in this opening and extends outwardly as shown and is providedwith an interior annular shoulder 14 preferably intermediate its ends. Asocket holder, or socket receiving member 15, fits into thisSpecification of Letters Patent.

sleeve or neck 13 and turns or rotates freely therein; the inner end ofsaid holder being flanged outwardly at 16, to engage and turn upon theinterior shoulder 1 1, and an eX- terior bead 17 on the holder or member15, engages the outer end of the sleeve 13, and thereby preventslongitudinal movement of the holder within the sleeve, but permits thefree and easy rotation thereof. This ex- ,terlor bead 17 can be appliedto the outside of holder or can be rolled integral therewith as desired.This freely rotatable member 15, is intended to receive the ordinaryincandescent lamp socket 12, and near its outer end is formed with aninterior annular stop shoulder 18, against which the shoulder 19, of thesocket cap abuts when the socket is inserted in the socket holder orreceiving member 15 thus properly positioning the said socket; and inpractice we so dimension the sleeve or neck 13 and socket holder 15 thatthe lamp, will be centered in the reflector 10 when the socket or lampis properly positioned and secured, and this centering of the lamp inthe reflector is very advantageous in a device of this kind.

The holder 15 is slotted at 20, to accommodate the key of a key socketor the eyelet guide of a pull chain socket, and may of course, beomitted from holders intended to receive keyless sockets only. The outerend of the socket holder is threaded as shown at 21, and for the purposeof securely fastening the lamp socket within the holder and supportingthe same therein, I provide a flanged threaded ring 22, the flangethereof engaging the shoulder 28 of the socket cap and the threadedportion engaging the threads 21 on the end of holder and binding saidparts together.

Other forms of fastening means may be employed to secure the socket inthe holder, but the form illustrated is preferred on account of itssimplicity and ease of manipulation.

The connection herein shown and described properly positions the socketand lamp in the reflector, placing the lamp directly in the center ofreflector; and the rotating connection enables one to turn the reflectorat any desired angle with reference to the lamp, and direct the light inany direction. Furthermore, the socket is positively supported withinthe holder by means therein, the lower end of said socket holder beingthreaded and a flanged threaded ring adapted to engage the threaded endof the socket holder and maintain the socket therein.

2. A reflector having an opening therein, a sleeve fitted in saidopening, said sleeve Copies of this patent may be obtained for fivecents each, by addressingthe Commissioner of Patents,

LAURITZ W. ANDERSEN.
